Four species of Cicuta (family Umbelliferae) are recognized for North America: C. maculata L. (2n = 22), C. douglasii (DC.) Coult. & Rose (2n = 44), C. virosa L. (2n = 22), and C. bulbifera L. (2n = 22). Cicuta maculata has 22 large somatic chromosomes, C. virosa has 22 small somatic chromosomes, C. bulbifera has 22 medium sized chromosomes, and C. douglasii has 22 large chromosomes and 22 small chromosomes. Four varieties of C. maculata are recognized: var. maculata, var. angustifolia Hook., var. victorinii (Fernald) Boivin, and var. bolanderi (S. Wats.) G. A. Mulligan, stat. nov. Cicuta mackenzieana Raup is considered conspecific with C. virosu. The nomenclature, distribution, and relationships of the North American species are given together with an identification key to species and varieties.

Diving Beetle

AbstractThe first of a planned series of papers revising the Nearctic species of the predaceous diving beetle genus, Agabus Leach, is presented. The genus is defined in the broad sense of Sharp (1882) and Fall (1922). The North American species are divided into species groups and diagnostic characters for group recognition are summarized in a key. Assignment of species to these groups is indicated in a checklist of North American species. The ambiguus-, tristis-, and arcticus-groups are defined, their relationships discussed, and included species revised. The ambiguus-group, which is restricted to North America, contains the species A. ambiguus (Say), A. strigulosis (Crotch), A. erythropterus (Say), A. austinii Sharp, and A. klamathensis sp.nov. The tristis-group, which has a Holarctic distribution, contains two species in North America, A. tristis Aubé and A. leptapsis (LeConte). The Holarctic arcticus-group is represented by A. arcticus (Paykull) and A. anthracinus (Mannerheim) in North America. For each species, patterns of variation are described, the North American distributions mapped, and ecological information summarized.

Species Groups

AbstractThe North American species of Dicladocerus are revised. Twelve new species from North America and one from Japan are described and illustrated: alaskensis, australis, prealatus, occidentalis, exoteliae, epinotiae, betulae, vulgaris, nearcticus, pacificus, japonicus, and terraenovae. The species attacking larch casebearer are nearcticus, pacificus, terraenovae, all Nearctic, and japonicus and westwoodii, Palaearctic. Relationships of species-groups in North America are discussed. A key to species, and host records are included.

Ips Calligraphus

AbstractIps calligraphus (Germar), I. ponderosae Swaine and I. interstitialis (Eichhoff) represent one variable species with the oldest name, Ips calligraphus (Germar) taking precedence. Ips calligraphus can always be recognized by the six spines on each side of the declivity. All other species in North America have less than six spines on each side.

AbstractThe genus Ips is one of four closely related genera in the tribe Ipini, sub-tribe Ipina (De Geer 1775, Balachowsky 1949, Nunberg 1954, Hopping 1963). There are now 32 species of Ips recognized in North America, with a few more as yet undescribed. This paper defines the groups of closely related species with observations on the group relationships of species from other parts of the world. Work is in progress to define the North American species in each group.

The Byrrhidæ of this continent have received a comparatively small share of attention at the hands of systematists for many years, so that it is not at all surprising to find novelties among recently-collected material. Two new forms of the genus Pedilophorus have recently been detected among the accumulations in my cabinet, both of them from the west; no doubt still others remain to reward explorers of the mountain ranges and of the northern districts. The European fauna contains ten species, while but four were previously known from North America.

AbstractThe name Enaysma Delucchi, 1954 is synonymized with the name Achrysocharoides Girault, 1913. Achrysocharoides is divided into two species-groups, guizoti and gahani. Fifteen North American species are recognized, including five that are new: A. reticulatus, A. bisulcus, A. albus, A. tetrapunctatus, and A. intricatus. A key to species, host lists, and distributions are included.

First Time

All macropterous species of Aptilotus Mik are keyed, with descriptions of two new macropterous North American species, Aptilotus pogophallus and A. nigriphallus. New distributional records are given for other North American species, and brachyptery is noted for the first time in A. luctuosus (Spuler). Four new macropterous species of Aptilotus (glabrifrons, spinistylus, rufiscapus, and binotatus are described from Nepal. The relationships between the North American and Nepalese species are discussed. Minocellina Papp is synonomized with Aptilotus, and the two species formerly in Minocellina, A. thaii (Papp) and A. besucheti (Papp), are thus given as new combinations. Limosina carbonicolor Richards, from Ethiopia, is redescribed and transferred to Aptilotus.
